<p>OSSL_CMP_MSG_http_perform - client-side HTTP(S) transfer of a CMP request-response pair</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code> #include &lt;openssl/cmp.h&gt;

 OSSL_CMP_MSG *OSSL_CMP_MSG_http_perform(OSSL_CMP_CTX *ctx,
                                         const OSSL_CMP_MSG *req);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>OSSL_CMP_MSG_http_perform() sends the given PKIMessage <i>req</i> to the CMP server specified in <i>ctx</i> via <a href="../man3/OSSL_CMP_CTX_set1_server.html">OSSL_CMP_CTX_set1_server(3)</a> and optionally <a href="../man3/OSSL_CMP_CTX_set_serverPort.html">OSSL_CMP_CTX_set_serverPort(3)</a>, using any &quot;CMP alias&quot; optionally specified via <a href="../man3/OSSL_CMP_CTX_set1_serverPath.html">OSSL_CMP_CTX_set1_serverPath(3)</a>. The default port is 80 for HTTP and 443 for HTTPS; the default path is &quot;/&quot;. On success the function returns the server&#39;s response PKIMessage.</p>

<p>The function makes use of any HTTP callback function set via <a href="../man3/OSSL_CMP_CTX_set_http_cb.html">OSSL_CMP_CTX_set_http_cb(3)</a>. It respects any timeout value set via <a href="../man3/OSSL_CMP_CTX_set_option.html">OSSL_CMP_CTX_set_option(3)</a> with an <b>OSSL_CMP_OPT_MSG_TIMEOUT</b> argument. It also respects any HTTP(S) proxy options set via <a href="../man3/OSSL_CMP_CTX_set1_proxy.html">OSSL_CMP_CTX_set1_proxy(3)</a> and <a href="../man3/OSSL_CMP_CTX_set1_no_proxy.html">OSSL_CMP_CTX_set1_no_proxy(3)</a> and the respective environment variables. Proxying plain HTTP is supported directly, while using a proxy for HTTPS connections requires a suitable callback function such as <a href="../man3/OSSL_HTTP_proxy_connect.html">OSSL_HTTP_proxy_connect(3)</a>.</p>

<h1 id="NOTES">NOTES</h1>

<p>CMP is defined in RFC 4210. HTTP transfer for CMP is defined in RFC 6712.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>OSSL_CMP_MSG_http_perform() returns a CMP message on success, else NULL.</p>
